介绍了煤矿井下泵房监控系统转化为一个液位控制系统的实现方法。液位控制系统具有非线性、上升时间长、滞后现象的特点,难以建立其具体的数学模型,为此提出采用模糊控制的方法实现。结合泵房实际情况和现场操作人员的经验,设计了控制水泵启停数量的模糊控制器,提高了系统对井下涌水量变化的反应能力。 This paper introduces how to realize the monitoring system of coal mine underground pump into a liquid level control system. The liquid level control system has the characteristics of non-linearity, long rise time and hysteresis, so it is difficult to establish its specific mathematical model. Therefore, the fuzzy control method is proposed. Combined with the actual situation of pumping station and the experience of on-site operators, a fuzzy controller was designed to control the number of start-stop pumps, which improved the system’s ability to respond to the variation of underground water inflow.
